I am making a website for balloon delivery. I need the clients to be able to pick which balloon they want us to include in the delivery and what colors to go with that balloon in the bouquet. The best way i can think is to have a extra checkout process or add it as a attribute. The problem is with attributes is we have over 200 Mylar balloons and 20 colors of latex. To have that many attributes would not look good at all! I either need to find a way to organize the attributes so it hows categories to organize the attribute or have a separate page in the checkout where they chose it after they chose the size of balloons. The problem is i cant find a way to do either. What is the best solution and where can i go to learn how it is done?
